"How the hell is your brother bigger than you!"
"I have no idea! It's crazy how big his cock is."

"Are you sure he won't mind you using his body"
"He won't, he was mine and we agreed to not fuck up each other's life. I mean, we never specify anything about having a little fun in each other's body. And he doesn't need to know what I did with his body."
"Fair enough. Let me touch that monster! Geez, it almost seems fake!
"H-hey! Don't pull it too hard. That shit's sensitive!"

"Ops, my bad. I will make it up to you by giving you a little something"
"A-ah! F-fuck! Y-your blowjobs are always the best! F-fuck, how the hell can you deep throat it! It's t-too long!" 

 

It's not every day that your boyfriend gives you head in your little brother's body. But I have make this a more common occurrence! My brother's cock feels amazing. It's so much more sensitive than mine. God, I'm already losing my mind, and it's only a blowjob! I can't wait to feel this inside my boyfriend's hole. It will feel amazing. The only thing I need to worry about is not cumming too soon. But by the many times I have heard my brother masturbate I can tell I can cum at least twice without having to take a break. I'm loving my new body. I wonder how my big brother is doing. He is probably jerking off alone with his smaller tool. What a loser.
